The root flare of a tree is the transition point between the trunk and the roots. It is a good sign when the root flare is exposed as that generally means the roots are spreading closely enough to the surface to obtain nutrients and oxygen. Most natural-grown trees (as in trees that aren't transplanted from a nursery) grow with the right amount of root flare.
However, many landscaping services fail to take into account the depth they're planting at when they're planting trees. More often than not they plant a tree too deep, which can lead to sometimes fatal health problems such as Root Collar Disorder.
If you don't see a root flare on your tree, it might be planted too deep, and on its way to an early death. Call us to discuss solutions!
